Strange to say, however, nothing living can be dredged 

 near it, therefore could the cable be seen at the bottom of 

 the sea it would present the appearance of a long line of 

 oysters and other shell growth interspersed with weeds, 

 passing over a vast field of mud. 



" The dredge used in making the collection is of wire 

 netting, the bag having an iron mouth, for boat use ; the 

 mouth would be 2ft. x 6in. made of flat iron (2in. x %in.), 

 the top and bottom being flattened out and made sharp, 

 the wire net bag about 2ft. deep, with J^in. mesh. The 

 rope for towing is attached to a chain bridle, made fast to 

 to the four corners of the frame."

Long. 1 3*50, lat. 4 mm. 



Hab. Malcolm Inlet, Persian Gulf, 10-12 fathoms. 



A whitish shell, tinged with pale ochreous ; attenuately 

 fusiform, eight-whorled, whorls somewhat swollen, spirally 

 closely punctate, the punctuations stained with pale 

 ochre, mouth oblong, lip simple, columella internally 

 once-plaited. 



A very graceful shell, and evidently a Leucotina, 

 though at one time we had fancied it came nearer 

 ActcBopyramis. Much confusion exists at present as to 

 the limitation of these two genera, and no solution will be 

 found to this difficulty till the animal is studied, when, 

 naturally, the wide distinction between the opistho- 

 branchiate y^<;/^<?;^/^<^ as compared with the Pyramidellidce, 

 will be seen at once. Conchologically, the chief distinc- 

 tion seems to be in Leucotina, the uniform punctate
